Production of Polarized Bremsstrahlung

The following figures are obtained using the formula of M.May and G.C.Wick (Phys.Rev.81(1951)628) for polarized bremsstrahlung production with electrons.

	This figure shows the degree of polarization for four different electron beam energies in dependence of the γ-energy (x-axis) and the emission angle θ (y-axis).
	Degree of polarization for different incident energies and collimated with the 230 cm Al collimator. A value of 0.5 refers to unpolarized photons.
	Degree of polarization for four different incident electron energies and 5 photon energy bands between zero and the maximum photon energy. The red hatched area denotes the angular range cut out by the opening angle of the Aluminum collimator for a given electron beam deflection angle of 1/ g. The beam spot has a Gaussian width of 2.35 mm FWHM.
	Realistic GEANT MC simulation for the electron beam spot size at the beam stop for Carbon. The contour lines show equi-intensity levels with the color code mentioned below the plot. The bold numbers inside each figure show the per-mille fraction of the total beam power deposited outside a beam pipe diameter of 90 mm at the location of the Beryllium exit window. The radiator thickness has been chosen to be 10-4, 10-3, and 3*10-3 of the radiation length in each material.

	GEANT MC simulation for the electron beam spot size at the beam stop for Niobium.
